Today, I have tried to upgrade from 7.4 to 7.5 (git pull; make ...)
I have a problem with the optional package coxeter3 (it does not compile).
Before trying to solve this problem with coxeter, I would like to know
if there is a canonical way to remove coxeter3 from sage tree to finish
the build c
I used Sage sometime around 2005 +/-5 and had a user name and password. Now
my login doesn't work and I can't even register.
I had a bunch of work saved on the site and I downloaded it too in case the
site lost it. Years ago the stuff could have been uploaded and restored.
I don't know if the

IMHO you should be able to finish build by (repeatedly) running make.
(It would in the end give you working Sage, although make will report an
error in the end)
Just in case, coxeter3 installs in 7.5 just fine for me (on a gentoo linux
box)

I would like to know how to handle with this issue. Consider a function
f=sqrt(cos(x)^3 - 3*cos(x)^2 - cos(x) + 6). It is possible to deal with
this function for standard procedures like numerical_integral in (-1,1). If
one considers f.canonicalize_radical() it is presented as sqrt(cos(x)^2 -

Dear friends,
I was using powerdot class for presentation and used sagetex package to
plot the math functions and tried to insert
but it created the sage-plot directory and sage worked fine on the
.sagmath.sage file. The problem is the created plots are not inserted in
the dvi --> ps-->pdf se
Hellow! I have problem: I need to solve equation with one variable, but
solution must be complex number. "find_root()" and "root()" in
scipy.optimize can't do it. Help me please.

root() from scipy.optimize should work:

The online site where I worked with SAGE (sagenb.org) was taken down
because of spammers according to

I had noticed some restrictions and comments about it back then. I went

If your equation can be solved exactly,
the standard Sage way would be something like this:
sage: var('y')
y
sage: solve(y^2==-2,y)
[y == -I*sqrt(2), y == I*sqrt(2)]
sage: (y^2+2).roots()
[(-I*sqrt(2), 1), (I*sqrt(2), 1)]
sage: (y^2+2).roots()[0]# one of the roots exactly, with

Putting limits in /etc/security/limits.conf (or in files in limits.d) works
right up to Sage 7.3. Namely, if a user performs a strong computation
(memory or CPU time), the system stops the computation when the limit is
reached; usually one needs to quit the worksheet, but it is possible to

That's strange and annoying. It used to be that
